While I did go to Dr Sadeghein office, the procedure was not done by him. I would have preferred to have him do the procedure, although he said everything looked very good on root canal. He did the follow up exam and I found him very nice, easy to talk to and I felt confident with what he had to say. Office has digital x-rays and staff are nice. As far as pain for root canal - procedure wasn't painful. Did have some pain after - but think my case is not typical.
